The newest additions to the NanoArc® product line help formulators meet the rigorous scratch and mar resistance requirements of very thin, highly transparent coatings. These products are designed for ultraviolet (UV) cured coatings used on electronics and wood, and in a variety of graphic arts applications. This comprehensive product offering, featuring various sized nano and sub-micron alumina dispersed in commonly used monomers, significantly improves the scratch and wear resistance of coatings used to protect thousands of products, from cell phones and computers to furniture and high sheen magazine covers, providing improved durability while preserving high optical clarity and gloss.

Nanophase's proprietary manufacturing process delivers highly stable dispersions that allow formulators to easily incorporate the appropriately sized aluminum oxide particles into a coating. These products are designed for optimum compatibility with the other components in the coating, so that the particles remain well dispersed and non-agglomerated. Unlike other additives, NanoArc® Aluminum Oxide dispersions are active at low loading levels and do not negatively impact the application process or the mechanical properties of the coating.

Nanophase plans to showcase its new NanoArc® Aluminum Oxide dispersion solutions at the European Coatings Show being held in Nuremberg, Germany March 28 – 31, 2011. A detailed description of the NanoArc® family of products can be found on the Nanophase website, www.nanophase.com or by contacting Sales and Marketing at 630-771-6709 or sales-support@nanophase.com.
